About

I am Rodrigo Rodrigues da Silva, usually Rodrigo Pitanga online. I build and operate systems at the intersection of AI infrastructure, software freedom, and education.

The recurring problem in my work is not simply automation. It is how to make a system legible enough that people can understand what happened, test it, assign responsibility, and improve it. That thread runs from GNU software freedom and open hardware through education and school operations to PaveDB, Flymmatik, hanzup, Planno.school, and bncc.click.

I am an active member of Garoa Hacker Clube. Metamaquina is inactive today, but its work remains published on GitHub. I was a former maintainer of GNU LibreDWG, whose continued work is visible in its GitHub repository. These are not separate credentials or a catalog of affiliations: they are part of the same Signal / Action thesis, in which software freedom, inspectable mechanisms, and shared artifacts make it possible to turn signals into responsible action.

I am based in Rio de Janeiro, Brazil. I have worked as an engineer, educator, product builder, and technology executive. The labels change; the operating question is stable:

What must be visible, testable, and governable for a signal to become a responsible action?

This site is where I develop that question in public. It is a personal publication, not a Flowlexi product site. The projects appear here as evidence and working material, not as a corporate catalog.
